It is not a motor-protective breaker — use it on the control supply side, not the load side of a contactor. Rated for 0.5 A at 35 °C, the breaker derates to 0.47 A at 40 °C and 0.42 A at 55 °C, so if the panel ambient runs warm, factor that into the load calculation. This breaker is certified to IEC / EN 60898-1 and IEC / EN 60947-2, with a UL 1077 supplementary-protector listing. The neutral pole is switched (1P+N), so this breaker disconnects both line and neutral — required in some regional wiring codes for final circuits. For buyers comparing across the SENTRON 5SY family, the 5SY7210-7CC is a higher-current sibling (10 A, C-curve, 2-pole) that shares the same 2-MW footprint and terminal layout. If your BOM calls for 0.5 A protection, the 5SY6505-7 is the correct order code — the 5SY7210-7CC will not drop in without changing the upstream protection coordination.","metaTitle":"Siemens 5SY6505-7 SENTRON MCB, 0.5 A, C-Curve, 2-Pole","metaDescription":"Siemens 5SY6505-7 SENTRON miniature circuit breaker, 0.5 A rated, C tripping characteristic, 2-pole (1P+N), 6 kA (EN 60898) / 30 kA (IEC 60947-2), IP20, halogen-free.
